Letters Patent No. 97,013, dated November 16, 1869.

IMPROVEMENT IN THE MODE OF ATTACHING SEATS TO WAG-0N5.

The Schedule referred to in these Letters Patent and making part of thesame.

Be it known that I, DAVID J W'ILCOXSON, of Milan, Erie county, in theState of Ohio, have invented a new and improved Key for Securing inPlace Slotted Tenons; and I hereby declare the following ,to be a fulland exact description thereof, reference being had to the accompanyingdrawing, forming part. of this specification.

The nature or essence. of my invention consist-sin providingtbr astandard, riser, or other fixture, to be secured to its hearing orsupport by one or more slotted tenons, sliding beneath a plate, or in arecessed mortise,a key connected to the. standard by a slot and pin.

The arrangement and operation of the device will be fully set forthbelow.

In the drawings hereinhe'fin'e meutioned- Figure 1 is an elevation oiv aspring-riser or standard with its bearer and key.

Figure 2 is a plan of the bearer,';showing the mortises through theplate. and, by dot-ted lines, the recesses beneath the top plate.

The standard or riser A, supporting the spring G, is provided with theslotted tenons 0,1), and c, and the bar or bearer B, with the mortiscsa, b, and 0', ex-

tending on one side under the plate I), (as shown in i dotted lilies oniig. 1,) so as to receive the projecting portion oi'the tenons below theslot 0.

To one of'thesc tenons, as a, I apply the key F, secured to the riserabove the tcnon, by means of the pin h, passing through the projectingshoulders iof the key, and through the slot It, in the riser A.

Vhen the riser or standard is lowered, for the tenons to enter themortises, the key 1" is stopped by the plate D, the pin it sliding up inthe slot k, and the key takes the position shown by dotted lines on fig.1.

The riser A is then pushed iorward until the plate D enters and iillsthe slots 0, when the key F is slipped down through the plate D, behindthe tenon (l, to its former position, relatively to the standald A, andthus secures all the teuons in their places, and, consequently, thestandard is firmly secured upon the bearer B. I

To release it, the key F is slipped up again out of the mortise, and thestandard may then be drawn back, and the tenons lifted outot' theirrespective moi:- tises.

By this simple construction and arrangement, I provide an efiicient key,which remains connected to the standard,bnt whielnwhatever its positionmay chance to he, offers no obstruction to the entrance of the tenon,and only requires to he slipped down to its place, when the standard hasbeen properly adjusted.

The foregoing being, a description of my improved slotted tenon-key,

What I claim, and desire to secure by Letters Patent, is as follows:

In combination with the slotted teuon a, the key F, for securing it inplace, when said key is held by a pin, h, sliding in a slot, If,substantially as herein set forth. 7
